What's left behind the scenes

If you try to skip the series intro in the Paramount+ app, the captions "Skip Intro" and "You Will Be Haunted" appear on the screen.
The series shows mosaic pieces, but they are very difficult to notice—for example, in the very first frame of an episode or in the brightest part of the frame. No mosaic piece is shown in the pilot episode, while the number of pieces in the remaining episodes varies from 3 to 8.
